Abstract
Description
図3に示すような嵌合関係となる金属製のスリンガ14及び内輪部材6を準備し、スリンガ14の出隅コーナー部14cにディスペンサーによって一液硬化型シリコーンエラストマーを吐出塗布させ、150℃で10分間焼付け硬化して、層厚dが0.02〜0.10mm(0.04mmが中心)の環状シール部14dを形成した。そして、該内輪部材6にスリンガ14を図3に示すような状態に嵌合させた。この時の嵌合締代(半径値)は、0.02〜0.15mmとした。また、内輪部材6の嵌合部に軸心方向に沿った深さ0.02mmの傷を付け、同様にスリンガ14を嵌合させた。これら傷のないもの及び傷のあるものの嵌合構造体を、加圧環境下においてエアリーク試験を実施したところ、いずれも内圧0.4MPaまで加圧しても、エアリークはなかった。
実験例と同様のスリンガ14及び内輪部材6を準備し、前記環状シール部14dを形成させていないスリンガ14を、外径面に傷のない内輪部材6と前記と同様に傷を付けた内輪部材6とにそれぞれ嵌合させて前記と同様にエアリーク試験を実施した。傷のないものの場合、内圧0.3MPa程度でエアリークがあり、傷があるものの場合内圧0.1MPa以下でエアリークがあった。
各種粘度の前記エラストマー剤を準備し、ディスペンサーによって試験片に吐出塗布させて硬化させ、硬化させる過程における環状シール部の成形性について評価試験を行った。図15はその評価試験の結果を表に纏めたものである。図15において、成形性の評価は、試験片を立てた状態でエラストマー剤を塗布して、エラストマー剤が流れるか否か、また、ディスペンサーによる塗布を停止し、被塗布部からノズルを離す際にエラストマー剤が糸引き現象を生じるか否かを目視判定することによって行った。成形性評価の欄において、×は、前記流れや糸引き現象が生じ、環状シール部がシール性にも影響を及ぼす程の不均一な形状となったことを意味する。○は、若干の流れや糸引き現象が生じるが、環状シール部が所期のシール性を保有するものであることを意味する。また、◎は、流れや糸引き現象が生じず、環状シール部がその周方向において、所期の均一な形状に形成されることを意味する。図15から、エラストマー剤の塗布時の粘度が20Pa・S以上であることが望ましく、100Pa・S以上であることがより望ましいことが理解される。
図4(a)の例では、環状シール部14dの形成部位としての出隅コーナー部14cの断面形状が平坦な面取り形状とされ、図4(b)の例では、出隅コーナー部14cの断面形状が凹曲形状とされている。出隅コーナー部14cの形状をこのような形状とすることにより、図3の形状に比べて、環状シール部14dの中央部の層厚dを厚くすることができる。これらの例のスリンガ14も、内輪部材6に対して白抜矢印方向に沿って嵌合されるが、このように中央部の層厚dを厚くすることにより、嵌合時に嵌合部に介在される環状シール部14dの一部(内輪部材6との重なり部分)の逃げ代が大きくなり、この部分の圧縮弾性変形が円滑になされる。図4(b)のような形状とする場合は、環状シール部14dの塗着安定性が増すと共に、層厚dを多少厚くしても前記逃げ代の作用によってせん断応力が強く作用することがなく、前記嵌合時における環状シール部14dの破断の懸念も少なくなる。
シールリップ部材16を一体固着した状態の芯金15は、その円筒部15aをして、外輪8の内径部に白抜矢印方向に沿って嵌合される。(a)の例では、芯金15の円筒部15aの嵌合方向後方側外周縁部15cの断面形状が凸曲形状とされ、この部分が環状シール部15dの形成部位とされている。環状シール部15dは、前記と同様に、エラストマー剤を塗布して硬化させることによって、層厚dが前記設定値になるよう形成される。芯金15の白抜矢印方向に沿った嵌合により、環状シール部15dの一部(二点鎖線)が圧縮された状態で、外輪8と芯金15との嵌合部に介在される。従って、外輪8と芯金15との嵌合部が密封され、外部からこの嵌合部を通じた軸受空間1a(図1、図2参照)内への泥水等の浸入が阻止される。
環状シール部15dの形成態様は、例示のものに限定されず、図4(a)(b)、或いは、図5(b)の例と同様に構成することも可能である。
図14に示すような環状シール部21pの形成態様は、図11〜図13の例においても適用可能である。
